IMPROVED SUGAR-EVAPORATOR.

Specification forming part of Letters Patent No. 38.254, dated April :21, i863.

T0 @ZZ whom t may concern,.-

Be it known that we, CHARLES O. WEST, ELIEL WEST, and JOHN CAREY, all of Martinsville, Clinton county, Ohio, have invented a new and useful Improvement in Saccharine- Evaporators; and we do hereby declare the following to be a full, clear, and exact desc-ription thereof, reference being had to the annexed drawings, making part of this specification.

The first part of our invention consists in a peculiar device employed in connection with pans running on wheels, to vary their distance from the fire and permit them to rest closely down upon the furnace-walls while in operation.

The second part of our invention consists in a device for tempering the heat to the final boilingpan.

Figure l is a perspective View of our apparatus. i Fig. 2 is a perspective view of the furnace. i

The first boiling-pans, CVD, areiixed over the hottest part of the furnace A, and discharge by a gate, E, or otherwise, into one of the final boilers or teaches F F, which are placed at a lower elevation with that object. The first boiling-pans, C D, have a level or nearly level metallic bottonn G, in contact with the fire.

In order to facilitate the solidiiication of the scum and other feculencies and their disengagement from the fluid mass, 'and thus avoid taint and scorching, we form the sides H of the first boilers of wood, and out of direct contact with the fire, and at an angle so slightly removed from the horizontal as, While permiting the reuX of the juice, to arrest or detain the impurities, which may be removed from time to time by means of a scraper, I.. The shelving sides or ledges H may be placed at any inclination that will effect the above purpose. In practice we have found a rise of seven inches in two feet to be effective.

Secured in a transverse and level position to the top of the furnace are two iron bars, J J', having depressions j attheir mid-lengths and ends, respectively.

The twin pans FF are secured permanantly together, 4and are supported and guided upon the track J J by means of iianged wheels K.

Vhen in use for boiling, one or other pan is allowed to rest firmly down upon the opening B of the furnace, in consequence of the wheels K occupying the depressions j; but the removal of the pans from the depressions onto the level portions of the track acts to elevate them slightly from the'furnace. This simple provision enables the operator to instantly arrest any tendency to Scorch, and also facilitates the shifting of thepans. Thus the motion which places over the furnace a pan that has been newly filled from the gate'E acts at the same time to remove the pan of inspissatcd Sirup clear of the fire, so as to allow its contents to settle without burning, and to be discharged through spile or faucet M into spout N, whence it may be collected in barrels or otherwise. l

The shifting of the pans F F may be effected by means of a winch, O.

l? is a fender to deliect the iiame from immediate contact with the bottoni ofthe teachc. Ve claim as new and of our invention-` l. The two iron bars J J', provided with depressions j, and inclined planes at their mid lengths and ends, respectively, for the purpose of allowing` one or other of the pans F F to rest firmly down upon the walls of the furnace when in use for boiling, and thus to receive the full'intensity of the heat, or to be elevated from the walls of the furnace and away from the fire when in danger of scorching, by simply shifting the pans on the track in the manner specified.

2. The arrangement of the deflecting plat or fender P, depending from the furnace-crown immediately in front of the teache-openi ng B, for the purpose set forth. l

y ln testimony of which invention we hereunto set our hands.
